BOX-GAR.

Specification of Letters Patent.

Patented Dec. 13, 1921.

Application led February 28, 1920. Serial No. 362,169.

Vroof structure b f which a union is effected between it and the end plate. The invention has for its object to provide mutual reinforcement between the end vplate and roof structure in order to resist weaving and thereby increase the durability of this joint and consequently increase the life of the car; a further object of my invention being to provide an equipment member for the repairing of box cars designed to produce the same mutual reinforcing effect.

To this end the invention consists of a structural member constituting a union between the end plate and roof structure of a box car by which mutual reinforcement and st-iffening of the end plate are obtained and strains and stresses due to the weaving of the cars are concentrated where the roof structure joins the end plate, this member producing in effect a relatively wide flexible gusset plate bolted to the purlins and having a depending flange bolted to the end plate of the car body. The effect produced is that all strains and stresses due to weaving and other distortions of the car roof are concentrated in the bolts fastening the flange to the end plate and consequently at a point below the roof and within easy access, both inside and outside of the car, for repairs.

For full comprehension however of my invention reference must be had to the 'accompanying drawings in which similar reference characters indicate the same parts, and' wherein in transverse sectional View my improved reinforcement member; and 'i Y i Fig. l is a fragmentary plan view of an end .of a car equipped with my invention.u

.F 1g. 5 is a detail fragmentary sectional yiew' of the reinforcement member illustrating the lip thereon. i i

Thoser parts only of a box car which are aected by my invention are indicated and as they are of well known structure faire not described in detail. These parts consist of side'plates 2, end plates 3, ridge pole `41:, purlins 5, side sheath 6 and end sheath 7. These parts are assembled as usual in the building of a boX car. p u A My improved end plate stiffener and reinforcement member consists of a comparatively thin and relatively wide sheet steel plate b of sufficient lengthto eXtend'in an arch from side plate to side plate ofthe box car and having horizontal end portions c to be clamped between the side plates and furrings and horizontal middleportion d for bolting to the ridge pole. One side edge of this plate has a relatively narrow depending longitudinal fiange e to be bolted to the end plate and the opposite edge has an upturned reinforcing lip f with spaces g for accommodating the purlins to which the sheathing is bolted through bolt-holes z arranged in staggered position as shown particularly in Fig. 4, the bolt-holes for accommodating the bolts by which the depending flange e is secured to the end plate, as indicated at c in Fig. 2, are located and in vertical line with the side edges of the purlins. The plate Z9 is of sufficient width to have a series of preferably three bolt-holes it for accommodating bolts 7c for fastening it to the 'purlins and a flange e although relatively narrow or shallow is of sufficient depth to, with its arch form', extend from within a short distance of one end of the end plate to within a short distance of the opposite end and from the bottom of the end plate at the sides of the car to the level of the ridge pole at the center, thus materially stiffening the end plate. The effect is that the plate b presents a brace of the gusset plate type while its relative thickness and consequent fiexibility resists weaving of the car and transmits to the flange e the strains and stresses which are thrown into the bolts m uniting this flange to the end plate at widely distributing points Vfrom end to end and structure' and end `plate and mutually rein- Ofrthe: end Vplate are easily accessible forV renewal when irresistible weaving Occurs, the ultimate effect 0f whichv when the resistance to 'breakage isfovercome is to shear these bolts.y

What I claim is as follows:

l. In a box car the combination with a roof structure and end plate thereof of a memberjeffecting a unionbetween the roof forcing the same, .such member consisting Of a comparatively wide and relatively thin plate secured to the roof structure and having a relatively shallow depending flange secured to the end plate.

2. In a box car the combination with side plates,l end plates, ridge pole, purlins vand side furrings, Of a'member effecting a union between the ridge pole, purlins and side furrings and the end plate, such member consisting Of a comparatively wide and relatively thin gusset plate extending in arch form from side plate to side plate and sethe said plate having at one side edge a longi-v tudinal depending flange, and bolts fastening the said flange to the'end plate at points in the vicinity Of the purlins.

Y, 3. In a box car the combination with side plates, end plates, ridge pole, purlins and side furrings, of a'member effecting a union between the ridge pole, purlins and side furf rings and the end plate, such member consisting of a comparatively wide and relatively thin gusset plate extending in arch form from side plate to side plate and Secured at its ends between the side plate and furrings and to the ridge pole and purlins, the Vsaid plate having at one side edge a longitudinal depending iange, and bolts fastening the said flange to the end plate at points in the vicinity of the purlins, and the said plate havingV at its Opposite side edge an upturned `reinforcing lip. Y Y f In testimony'A whereof I have signed my name tO this speciication'in the presence of twoA witnesses.
